Abstract


Strategic planning and execution at the Benti–Bagda Limestone Mine of M/s Jharkhand State Mineral Deve­lopment Corporation Limited (JSMDCL), India, could minimize the impacts of surface blasting on structures in nearby sensitive villages to comply with the regulatory requirements leading to resolving the complaints of villagers. Controlled blast design patterns were developed after thorough scientific evaluations using JKSimBlast simulator and blast-compliance software modules to determine the firing pattern, firing sequence and detonation time versus charge mass (kg) detonated for each of the three blast-safety zones. The study enabled the mine management to convince the local people to settle their long-pending disputes
